It's a video made to accompany a track by Eric Prydz and featuring a sample from Pink Floyd's "Another Brick in the Wall" - some good parkour and a message at the end - and all in moody black and white to save colour...

Just a few hours after that video was posted, Ollie Bray brought another video to my attention. This one features the same music track, but different images.
